My opinions themselves are plastic; constantly changing.

In the firework industry we use ABS in our mortars because they will stretch and rip if a firework explodes in the tube rather than shatter and turn into shrapnel.

ABS would be better in that regard, it has a higher plasticity and less likely to fragment. But the one in the OP is PVC. ABS pipe is black.

Edit: And I'm pretty sure ABS doesn't show either.

We used to make them out of PVC pipe from the hardware store

The word consuming is deeply unsettling in this context. More so than high velocity plastic shrapnel, which is surprising

Very human
